Series of shortcomings blamed in overpass collapse - CTV.ca Canada
The report, which was made public Thursday -- three days after it was submitted to the government -- found there were three main reasons for the collapse:
*A "total lack of quality control";
*Shoddy construction; and
*Low-quality concrete used to build the overpass, constructed 35 years ago.
One thread linked all three factors, Johnson said. People and organizations "failed to assume their responsibilities during construction (and) during the bridge's service life," he wrote in his report.
Johnson added that repair work in 1992 may have done more harm than good. Further, he said poor inspections sealed the fate of the overpass near Montreal.
